摘要：
Ultraviolet photoelectron spectroscopy (UPS) has been used to study methanol adsorption on ZrC(100) and (111) surfaces. It is found that methanol adsorbs molecularly on the ZrC(100) surface at room temperature. On the other hand, UPS study shows that methanol is dissociated on the ZrC(111) surface; methoxy species and completely dissociated atomic species (C, H and O atoms) are coexistent on the ZrC(111) surface, and complete dissociation is dominant in the initial stage of adsorption.
